Our Bangladeshi plotholders gave me some tiny chilli seedlings a couple of months ago. They were about 2" at the time. I think they saved the seeds themselves, they don't know what the variety is except that it is hot!
I brought them home and they are growing well on the kitchen windowsill.
4 of them are tall (about 16") and one is only about 5". They are obviously two different varieties.
These are the tall ones, with a close-up of a flower

and this is the short one and close up of the flower

The short one already has at least six chillies on, green at the moment.
I know this is difficult, but does anyone recognise what they are?
